But the operation principle of the locking pliers of the utility model self-locking and automatic unlocking can be described as follows:
1, pincers function
Workpiece is placed in the jaw, the user is to pressing down handle 6, the gear on the gear drive movable claw 2 on the handle 6 then, make jaw closed gradually to clip to workpiece, with hour rack 4 in the pilot hole of yoke 3 relatively to left movement, all the time be pressed under the effect of spring B on the tooth bar 4 and discharge ratchet 8, preventing that jaw from opening.After movable claw 2 touches workpiece, movable claw 2 and yoke 3 stop motions, in this whole process that clips to workpiece gradually, the angle of tooth bar 4 and lever 5 remains 165 degree.
2, auto-lock function
Cooperation is referring to Figure 21, Figure 22, because movable claw 2 and caliper 1 can not continue motion behind the clamping work pieces, when the further pressing handle 6 of user, to order about yoke 3 serves as axially motion down with pin 14, and a part that is positioned at the tooth bar 4 of yoke 3 pilot holes is subjected to downward pressure, and causing tooth bar 4 and lever 5 serves as that axle changes relative position with pin 15, rotational angle is to-177 °, inclined-plane in this hour rack 4 and the lever 5 is inconsistent, can not continue to relatively rotate, thereby realization is to the auto-lock function of workpiece.
3, unlocking function
Cooperation is referring to Fig. 1, Fig. 2, and after clamping and locking workpiece, the angle between tooth bar 4 and the lever 5 is-177 °.Promote cap 13 to front slide with thumb this moment, driving unlock button 12 rotates, then unlock button 12 moves downward the front end of release lever 11, thereby ordering about pin 15 moves upward, driving tooth bar 4 and lever 5 serves as that axle changes relative position with pin 15, make angle between tooth bar 4 and the lever 5 less than 180 °, thereby realize release.Continue to promote driving lever 7, the swing arm 71 on the driving lever 7 will promote to discharge ratchet 8 and move up, and make to discharge ratchet 8 and tooth bar 4 disengagings, thereby auto-lock function disappear; After auto-lock function disappears, under the effect of spring A, jaw will be opened automatically.
Cooperation is referring to Figure 19, Figure 20, and when released state, the lower inclined plane of the sharp mouth 1001 of lever controll block 10 contacts with the ramp of the pointed shape structure 53 of lever 5 rear ends, and causing lever 5 can not serve as that axle rotates with pin 18.In this case, the user gives handle pressure when clamping function, and the pilot hole of yoke 3 can only travel forward along tooth bar 4; Rather than directly move downward direct self-locking.Behind clamping work pieces, after promptly realizing clamping function, after the user continued to exert pressure, lever 5 can be given 10 1 active forces of lever controll block, make its rotation, up to breaking away from lever 5, to realize auto-lock function; When self-locking state (angle between tooth bar 4 and the lever 5 is-177 °), the ramp of the sharp mouth 1001 of lever controll block 10 makes pin 15 can not continue to move downward in the lower inclined plane contact of the pointed shape structure 53 of lever 5 rear ends, to strengthen coupling mechanism force.
